"I think he'll stand in front of any barrage of media questions and answer everything with clarity," Watson said. "I think some guys, certain guys, wouldn't have the clear understanding of how to explain their situation and at the same time communicate the obstacles going through it and the avenues where you can actually reach people."
Watson's thoughts echoed waves of national support. NBA players including Kobe Bryant, Manu Ginobili and Baron Davis tweeted their support, as did former Stanford classmates Chelsea Clinton and Massachusetts Rep. Joe Kennedy.
Jarron Collins voiced his support for his brother not long after the story was published.
"Very proud of you," he said on Twitter.
In a statement, NBA Commissioner David Stern said, "As Adam Silver and I said to Jason, we have known the Collins family since Jason and Jarron joined the NBA in 2001 and they have been exemplary members of the NBA family. Jason has been a widely respected player and teammate throughout his career and we are proud he has assumed the leadership mantle on this very important issue."
Watson said that in his mind, gays in the locker room would not be an issue. But over time the question of whether a professional athlete could come out and be embraced gained steam, with NFL players Chris Kluwe and Brendon Ayabadejo speaking in favor of supporting gay teammates. In recent weeks reports surfaced that a group of NFL players considered coming out.
Asked if players would object to a gay teammates, Watson said, "I think younger players who don't know him will have some issues, some personal issues, but at the end of the day a lot of guys don't get along anyway on an NBA team. So I don't think it really matters."
He added that the first player to come out is Collins a thoughtful statesman of the game will help smooth the transition into a world in which openly gay professional athletes play alongside straight ones.
"He's the perfect person," Watson said, "because he's the most intelligent, creative, responsible, kind, character guy that's probably in the NBA period."
Watson, like Collins, will become a free agent on July 1. Whether an NBA team signs Jason Collins, who wrote that he "still has something to offer," is not his motivation, Watson said.
"He's playing because he loves the game," he said. "I'm pretty sure he can get a job. It's not like he's an athlete who the game of basketball just defines him. ... I think the timing is perfect for him. I think it's more or less the freedom and just waking up with the clarity he has that he has delivered that message. I don't think it has anything to do with being signed or he even cares about that, honestly."
Watson and the Collins brothers committed to UCLA and coach Jim Harrick before Harrick was fired for violating NCAA rules with a dinner for the three recruits. The Collinses subsequently enrolled at Stanford, while Watson went on to a four-year career with the Bruins.
"I go against the gay stereotype," Collins said in the Sports Illustrated story written along with correspondent Franz Lidz, "which is why I think a lot of players will be shocked: That guy is gay? But I've always been an aggressive player, even in high school. Am I so physical to prove that being gay doesn't make you soft? Who knows? That's something for a psychologist to unravel. My motivations, like my contributions, don't show up in box scores, and frankly I don't care about stats. Winning is what counts. I want to be evaluated as a team player."
Watson said the piece rang true to Collins' nature.
"It was typical him." Watson said. "His delivery in everything he does, even his conversations, is very intellectual. He's very articulate in the way he speaks. He's a great communicator. There's no one better than him to take the forefront on this."
